我遇到了非常奇怪的问题：
我有一个模块，它适用于 magento 1.4.0.0 - 1.7
最近我有人说这个模块没有在后端显示。
这是 xml 布局代码
<reference name="content">
<block output="toHtml" type="syncer/adminhtml_mapping" template="wisepricer/mapping.phtml" name="wisepricer.mapping" />
</reference>
另一种 xml 布局的平静出现了。
我看到它找到了块类（如果你把 die 放在块构造函数中 - 它可以工作）。但是，如果您将 die 放入模板中-什么也没有。没有关于这个的记录。
模板 adminhtml/default/default/template/wisepricer/mapping.phtml 的路径
有任何想法吗？
谢谢

感谢各位大侠的回复，补充信息如下：
config.xml 中的块声明
<blocks>
<syncer>
<class>Wisepricer_Syncer_Block</class>
</syncer>
</blocks>
块类的一部分
<?php
